i, pi i i y V c). Specification forming Lntlof Lettera Patent No. 'gd, dated August' 3l, 1869.

Toall whom it may concern l I Ee itv known that I, L. F. PARKER, of the city of Davenport, in the county of Scott and State of Iowa, 'have invented a new and usefnl Machine for Binding Grain with Twine; arid l do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specilication, and to the letters of reference marked thereon, like letters indicating like parte wherever they occur. y

^ To enable others skilled in thei, art` ,to construct and use my invention., I will proceed to describe it.

My invention consists in a novel method of binding grain with twine as it comes in gavels from the platform of a harvester before it fallsV to the ground,- more particularly tobind grain ked to it by rake on my harvester patented December 1, 1868.

Figurel is a perspective view oimy machine. Fi 2 is a View of section `of rolling shaft to irregular spur-wheel, with lever-rod and rock lever driving hnotftying machinery. Fig. 3 is .section of knottying machinery, comprising pinion and cog-lever that drivedt; Fig. 4, a perspective view of circle on knot-tier and its projections and slot; Fig. 5, perspective view eflrnottier and pinchers on arm gi Fig. 6, per spective View of looper, showin` g side next t0 circle with groove; Fig. 7, knot astied in twine when passed. around gave). of grl-tinylliig. 8, irregular spur; wheel, side viewthigt), vertical view .ol' irregular spur-Wheel land 'its roliing shaft with levers attached.

In. constructing my machine lniakeia rectangular frame, A., with width corresponding to size of gavel, and length corresponding to width of platform on harvester and ilength ci' grain to be bound, and placel it in position to platform D, so that it shall-.i receive the grain as raked from it. One endliwfill besupported by finger-bar, While the other is in such position that the irregular spunwheel B shall he actuated by pinion on shaftand may, it on my harvester, Patent No. 84,5G7, drive the rake that brings gavel of grain tolbinder. On .this frame' the binder rests. The gavelis re i ceived into double concaves E and F, having cylinder-heads G and H, when immediately compressing strap I and twine J are passed around it by means of arm K. The compressingetrap I is permanently, though loosely, at-

tached around arm K; at sncient distance from its end not to come in contact with knottier. The twine J is/ta'ken up from holder L by means of y pinchers M on end ol' arm K, said pinchers M being opened by holder L, it being wedgeshaped, and catching' twine as they leave it, twine J projecting out 0i' hole at top ol' holder L. When arm K has carried strap I and twine/J around gevel, so that pinche'rs M are againfiinmediately below holder L, it stops and falls hack ontogspring-stop N, as seen in red lines on Fig. l, which stop it has moved back in passing up by it, until the knot is tied and twine cut off. The spring-stop is moved out of track of arm la by rock-lever (l just as knot is tied and arm falls back. Concave's E and F at the same time are carried back by force of lever D,"

on shaft U` of irregular Wheel B, acting upon .rod Y, that upon crank c and .its shaft to cylinder G, and by pitman it t0 crank f on shaft g to crank f, and pitman c' to crank j', and its shaft to concavelH, thus causing both concaves'lo revolve back about one-third revolution, and leaving an unobstructed passage for sheet' to ground, carried by its own weight and force of strap l, and its spring .D drawing around it. The concares are inmediately brought back to place by action, iirst, of their own weight, shaft being out of center; second, by force of spring Q in reverse of action ci rod Y. The arm l; is carried baci; to or near" its starting-point, irst, by the force of spring said irregular spur-wheel B to make regular revolutions when harvester is in motion and it is in gear. This spur-wheel B may be of any desirable size and number of cogs, according to 'size of pinion cn driving-shaft and spurwheel S, in which it meshes; but each of its revolutionsmnst perform the binding-process and bring concaves'to place at proper time to take up a proper-sized-gavel. 1t has 'a line of cogs on about 'two-thirds of its peripherytha't mesh nto ine suine number of cogs, less one left oit on the periphery of spur-wheel S, to which hrm K is attached. The remaining part of periphery of irregular spnr-wheel B has cogs ontiotV line with cogjs that mesh in spurivhcel S, as will more fully appear in Fig. 8 and Fig. 9, to permit its being driven regularly. Spur-wheel S, to which arm K is attached permanently, has same number oi.' cogs on periphery as are on section of irregular'r nur-wheel B, that meshes into it, less one, whiidw s le 't out, and in its space '.'i blank, a. This` 'ineuir, g n receives the first two cogs on sectifgili` of iiiregular spur-wheel B. Spur-wheel S liza -s a little over one revolution, carrying arm up to twine-holder L. When it stops revel ing the arm Kvfalls on spring-stops N, as sh: wn by dotted lines on Fig. 1, till knot is tied, wheinbeing now free, it revolves back allow sheet to fall, but is drawn to or nearplaee onstop by strap and spring m on concnvcfi@ tile vacant space n permitting it i0 be taken up ii' not quite to its place. Rollingsliaft C (is-ee Fig. il) drives the knot-tier, Fig'. n, by means ot' lever ci acting lupon rod d directly,` to carry it in one direction, and on rock-lever c, (see Fig. 2,) to cause the reverse motion. llt Aalso causes the cnhcaves E and F to revolve, to eject sheat b vi action of lever b iiigaiilst, end ot' rod Y, andl cranks, pitinen, and shafts, attached to rod d., move, as acted upon, by lever ev on roller-shaft G, rocklever 0., `and by, it sliding rack p forward and. back, to knot. Rod Y moves crank e and shat't to ebiicavejE, and also, by pitman h, crank f, shziitlgJcrank Q, pitman z', and crank f and shafli to concave F, all to eject sheaf when boundi. 1y

Spin-wheel S has arm K attached to it. It also h|as a hollow rollin g-shat't, X., permanently attached. Shaft of crank c on cylinder-head G passes through shaft X longitudinally, loosely. yThe cranks on concaves are prevented't'roni turning back by stops o, under them;A n'lhe strap l serves to compress the shear, and has one end attached to arm K, as described, the other to spring P, which causes, when drawn out, the pressure. The support T sustains concave E when gavel is pressed against it.

e. modiiication of this machine may be to havel the'twine carried by piuchers on a second arm at the opposite end, revolving around concave F and cylinder-head H, the same as erin ,lnowldoes around concave E, and actuated by machinery in the same way, so as to belberried? by connectingshaft and pinionsl froth spur-wheel S. Springs may he added to caiiryiigavel. over the opening between platforntstraps D and concaves, if desired.

The knot-tier is' com posed ot' a circle, l, having two projecting points, 7, on its periphery, withia depression between them, with disk presented to concaves E and F near center opening between them. ,This circle is on rolling shaft 3, running back to pinion 5 on its end,'iwhic`h, being moved by sliding rack p,

l e' 'y ecuaccauses the circle 1 to' revolve vertically, alternately forward and hack from about one-third to one-half a revolution'. The circle 11s perforated b v a semiciroular slot, 8, near its shaft to. allow it to move unobstructed by shaft 4, which passes through it. The pinion 5 on reverse end ot' shaft is alike perforated byslot 9 for shaft 4, which also passes through it. Circle 1 has a groove in its periphery about one-half its circuit, Where cutter rests, terminating in the slot or opening in the projecting points, where twine is cut by being brought against cutter 14. At the point on circle where points 7 project outward, and a little belowthe depression between them, this part of the circle with the points projects beyond the face of the circle l toward the concaves suicient to allow point of looper 2 to pass under or back of twine resting over depression between projecting points 7. (Sec Figs. 4 and 5.) The looper 2 (see Figs. 5 and 6) is on rolling-shaft 4, just below shaft 3 ot' circle l, at that end passing through slot 8 in circle l, at the reverse end passing tlgirough slot 9, in pinion 5 on circie-shalt 5%, to pinion 6 on itself, which', when carried by line ot coge on sliding rack jp, meshing into its top, revolves. This pinion 6 is less than cnc-half size of pinion 5, on shaft of circle l. Thus the motion of sliding rack ,p causes it to revolvel about once around while the pinion 5 revolves less than onehalf circuit in a reverse. direction, as it meshes into a line ot' cogs at its bottoni. Looper 2 rests on face ot circle 1., its hooi; projecting outside ot' and below points 7 on circle 1 when both are near bottom of vertical ci rcuit. When both pass each other at or near top of vertical circle, it only reaches to forward projection on face of circle 1 below depression between points 7 on periphery. The inside oi" looper 2 next to4 circle 1, near shaft 4, is grooved to conduct twine, groove running from under hook to a point nearly opposite, when it runs out on the face of looper 2. The hook of looper 2 sits out from face of circle 1, except at its point, far enough to allow passage of double binding twine around in groove. On its outer face it 'has a spring, 15, under which ends ot' twine pase when pointruns under twine. This spring is of such elasticity as to hold double twine',- while the loop is formed at ,the 'saine time, that it opens bypressure of twine less easily than twine is drawn from holder and pinchers on arm. *i

Guard 12 around knot-tier serves to'protec itfrom grain; also, as support to concaie-Ii when gavel is'prcssed against its side. *Out ter 14 is stationary on guard 12, andl rests in prepared groove in circle, and cutstwine when pressed against it by movementof circle l. Spool y10 holds twine, the end passing from, it to and through twine-holder L. Twine is held tt proper tension 'oy spring 1l, or its equivaent.` The manner ot' operating knot-tier is as follows: The 'pinchers M on arm take' up end of twine from holder L, and carry it around gavel of grain, when arm K 'reaches opposite side of concave, as shown on Fig.1, the twine being` drawn taut over circle in depression between points 7, lever on rolling shaft on irregular spur-wheel B; then," by rod d and connecting machinery, pushes sliding rack p forward, causing the circle 1 to revolve vertically to the left till it carries twine down past the hook on looper 2, vertically revolving in an opposite direction, and to a point at which it will receive the other end ot' twine between points as the arm comes up. The reverse motion is then applied to sliding rack p, and the circle 1 and looper 2` are carried in opposite 4directions back to first position, the circle 1 still carrying the twine, now double, between its points 7. The looper-hook revolving in an opposite direction, projecting, as it does, below points 7 on circle l, takes the twine nearer the gavel, and Winds it in groove around itself. Passing back of hook, it follows groove to face of looper 2. The hook on looper 2 meets the .twine held between points7 before the circle arrives at its destination, and, passing its point under it, takes it under thespring on its face, and passes on till the hook is pointed down. The circle 1 passes on till it carries the twine between its points, against cutter 14, and v1t is severed.

This leaves the ends under spr-ing on hook, and the loop around in looper-groove is drawn loose, and passes over the ends held by spring.

The sheaf, now falling, draws the twine intoV knot.

The knot tied is lying parallel, as they lead away from gavel when twine is passed around it.

Such tension as may be desired may be given to twine by spring 11 against spool l0, or by passing it around grooved wheel between spool and twine-holder, or spring against twine.

measure regulate the amount of slack required to tie knot, and the loca-tion ot' knot as between ends and gavel. A brush or other contrivance may be placed on guard 12, so that it shallretain twine in groove on looper 2 until ends have been taken by spring on hook; then having been pressed by the brush the Atwine is loose.
